INHALER.

SPECIFICATION forming part of Letters Patent No. 513, 1 53, datedJanuary 23, 1894.

Application filed April 1, 1893. Serial No. 468,676. (No model.)

To all whom it may concern: I

Be it known that I, WILLIAM B. SPENCER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Inhaler, of which the following is aspecification.

This invention relates to inhalers, and it has forits object to providemeans for placing several chemical primary substances having remedialvapors, and that are chemically incompatible, and rendering the sametheracurative influence of the several vapors.

invention consists of the construction and arrangement of the partsthereof as will be hereinafter more fully described and claimed.

In thedrawings: Figure l is a perspective view of an inhaler embodyingthe invention. Fig. 2 is a longitudinal vertical section of the same.Fig. 3 is a view similar to Fig. 2, with the spring-clamp removed. Fig.4is a detail perspective view of the clamp and the body detached fromeach other and showing the course of the air through the said body.

Similar numerals of reference indicate corresponding parts in theseveral figures of the drawings.

Referring to the drawings, the numeral 1 designates the body, which iscomposed of a series of continuous cells2, 3, and 4, of bulbous formconnected by contracted necks 5, and the bulb. 2 provided with an openneck 6 at its outer end. The outer end of the cell4 is formed with anopening 7, and centrally of 1 the cell 3 is an opening 8 in the sidethereof.

Within the neck 6 a cork or stopper 9 is loosely fitted, to which theouter end of a valve-rod 10 is secured, having thereon valves 11 and 12that engage the necks between the cells 2 and 3 and 3 and 4 to close thesame. Over the body is movably fitted a springclamp 13, havingangularly-bent ends 14, one of which carries astopper or cork to fitinthe opening7 of the cell 4, and the other engages the stopper or cork9. At the central part of the said clamp is mounted a stopper or closingdevice 15, that is arranged to coact with the opening 8 in the side ofthe cell 3, and by this means it will be observed that the openl/Viththese and other objects in view the ings 7 and 8 are directly closed bythe said clamp and the parts carried thereby, and the neck 6, togetherwith the necks between the cells 2 and 8, and 3 and 4, are indirectlyclosed by the action of the angularly-bent end 14 0f the said clampbearing against the stopper or cork 9. I

It will be understood that the inhaler is designed for use-in treatingcatarrhal and other forms of disease of the respiratory organs, and thecells as set forth are provided for the reception of a special orindividual medicinal agent or agents, which are fixed in situ in each Icell by means of surgeons wool, as at 16. In

the cell 4, for example, iodine in the scale or crystal form is placed;carmenthol in the cell 3; and eucalyptol in the cell 2, by inserting thesame at the opposite open ends of. the cells 2 and 4, and the opening inthe side of the cell 3. As thus charged, the inhaler is ready for use,and by reason of the-isolation of the vaporizing agents in separatecells, possibilities in vapor generation and dilfusion are obtainedwhich are almost completely stified by the chemical reaction that takesplace when Inedicinal agents are located in the same, or

more openly-connected apartments.

In use the open end of the cell 4 should be rection shown by the arrowsin Fig.4. The

air in passing through from cell to cell enters the nostrils saturated,as it were, with the essential substances occupying the isolated cells,thereby producing a therapeutic influence of a remedy so far asacurative action is concerned in catarrh and other forms of disease ofthe air-passages. Regardless of the behavior of the substances, thedevice shows that vapors may be both chemically and therapeuticallycompatible when their prototypes are not, on account, for the most part,of other matter withwhich they are associated and which does notvaporize,

It will be observed that the vapors from the-form of inhaler set forthare freshly comclasp is removed. when the inhaler is in use, and thecommunication between cells 2 and 3, and 8 and 4, will be regulated bythe operation of the valves 11 and 12. It will be understood thatacomplete closing of the cells in the manner set forth is not absolutelynecessary when the generating substances and their vapors are chemicallycompatible, but it 1s preferable even in this instance to close thecells because it greatly economizes the inhalents, for when kept closedrecharging is not so frequently required.

From what has been previously stated it will be seen that the threeseparate chambers 15 augment and expedite the capacity of vaporlzation,and also the regulation of constituent elements or changing of the same1n compounding to meet indications in practree or application aregreatly facilitated and simplified, and as a natural consequence betterresults are obtained in the way of cures than from the ordinaryinhalers. It brings greater possibilities from inhalers, is ..moreeconomical, less bulkyand more handy, per- 2 5 mits less odor whencarried in the pocket, and may be used in making applications with ahand bulb, compressed air apparatus, or drawn by the user in treatment.

Changes in the form, proportion, and the minor details of constructionmay be resorted to without departing from the principle or sacrificingany of the advantages of this invention. V

Having described the invention, what is claimed as new is- 1. In aninhaler, the combination of a series of cells of bulbous form and ofcontinuous formation communicating with each other and having exterioropenings, contracted o necks being formed between said cells, and a rodhaving valves thereon to engage said necks to close communicationbetween the said cells, substantially as described.

2. In an inhaler, the combination of a series of bulbous communicatingcells having contracted connecting necks provided with openings and alsohaving exterior openings, a rod extending through a part of said cellsand carrying valves to control the openings in the said necks, and aspring-clasp exteriorly embracing the cells and having devices inconnection therewith for directly regulating the exterior openings andindirectly controlling the rod and valves, substantially as described.

3. In an inhaler, the combination of a series of bulbous cellscontinuous of and communicating with each other, the terminal cellshaving end openings and the intermediate being provided with a sideopening, a filling in the said cells serving as a vehicle to carry themedicaments, a rod extending inward from one end and having valvesthereon to control communication between the cells, and a spring-claspembracing the said cells exteriorly and having angularly-bent ends toboth directly and indirectly control the exterior openings of the cellsand the rod carrying the valves, substantially as described.

at. An inhaler, consisting of a series of communicating cells havingconnecting necks and adapted to contain the medicament vehicle, a seriesof connected valves arranged to control the passages between the cells,and means for operating said valves, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

WILLIAM B. SPENCER.
